"I've been happy with the first month," said Posey, who did not have a chance at his first All-Star Game in 2011 because of a collision at the plate that ended his season in late May. "My ankle's responded great. I've been out there as much or maybe more than I hoped for."
The hitting hardly has been limited to those four, making the choice for whom to vote for to start in the July 10 All-Star Game a difficult one.
The Phillies' Carlos Ruiz is batting .313; A.J. Pierzynski of the White Sox carries a .309 average into the month of May. A.J. Ellis, playing regularly for the Dodgers, is at .291.
And there has been power, too. Mike Napoli of the Rangers, who hit 30 home runs last season, leads all catchers with seven this year, followed by the Orioles' Matt Wieters, who has hit six.
And there has been run production: Pierzynski had 17 RBIs. Wieters and Molina each has 15. Napoli and Ramon Hernandez of the Rockies each has driven in 14 runs.
Here's a surprise: Molina, never considered to be fleet of foot by anyone's imagination, is leading all backstops in runs scored with 14.
Still, most any manager will say that defense is the top priority -- calling a good game, holding runners.
"Right now he's doing a tremendous job behind the plate," Mets manager Terry Collins said of Thole. "I like where he's at. ... I don't want to change anything with the way Josh has played, because he's caught very well."
The D-backs' Miguel Montero has held opposing baserunners to a Major League-lowest 45.5-percent stolen-base rate. Pierzynski -- in his 16th season at age 35 -- is second with an even 50 percent. Seattle's Miguel Olivo and San Diego's Nick Hundley are up there as well, though Olivo is headed to the disabled list because of a strained groin.
It's one thing that the catchers are hitting. It's another that most of these backstops are established players.
Among the American Leaguers Mauer is a four-time All-Star. Pierzynski has played in two. Napoli has averaged 33 homers for every 162 games played in his career. Carlos Santana of the Indians and J.P. Arencibia of the Blue Jays continue to rise in the ranks.
Posey would appear to lead the way in the National League but he has plenty of company -- and competition -- on the ballot. There's Molina, a four-time Gold Glove winner and an All-Star each of the past three seasons. Ruiz and Hernandez have long been established starting catchers. Thole and Ellis are up-and-comers.
Lurking in the shadows is Atlanta's Brian McCann, who is off to a slow start with the bat but has been to the past six All-Star Games. Last year he batted fifth in the starting lineup.
